PAPER Box.

Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed October 22, 1915. Serial No. 57,244.

To all whom it may concern Be it known that I, HENRY A. JOHNSON, a

citizen of the United States of America, re-

siding in Kansas City, in the county of Jackson, State of Missouri, have invented certain new and useful Improvements in Paper Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in paper boxes, one of the objects being to produce a strong and simple paper box adapted for use in the shipment of articles by ex press or parcel post.

Another object is to produce a box of this kind having a simple closure adapted to be securely closed at all points around the body of the box.

Figure I is a plan View of a paper box blank embodying the features of my invention. Fig. II is a perspective view of the box formed by folding the blank shown in Fig. I. Fig. III is a vertical section of the box, showing the closure in its closed position. Fig. IV is a horizontal section of the box shown in Fig. II. Fig. V is a perspective view of the box illustrated in Figs. I and IV, showing the parts as they appear when the box is closed. Fig. VI and Fig. VII are perspective views illustrating other boxes made in accordance with the invention.

The box blank shown in Fig. I is a sheet of corrugated paper board, scored along the dotted lines 1 and 2, and provided with slits 3, to produce a front wall section 4 having side flaps5, a bottom wall section 6 provided with side flaps 7, a rear wall section 8 having side flaps 9, and a closure section 10 having side flaps 11. The closure section 10 is extended to produce a narrow front closure flap 12 provided with free extensions 13 which lie parallel with the side flaps 11.

In folding the box blank shown in Fig. I to form the box illustrated in Figs. II and V, the front and rear wall sections desig nated 4 and 8, respectively, are folded upwardly from the bottom wall section 6, and their side flaps 5 and 9 are folded toward each other, to form portions of the side walls of the box. The flaps 7, extending from the bottom wall section 6, are folded upwardly and fitted to the outer faces of the flaps 5 and 9. The flaps 7 are then secured to the flaps 5 and 9 by means of cement, or in any other suitable manner. This produces a'box body having a closure hinged to its rear wall 8. The sections 4, 6, 8 and 10 are in-the form of panels, and the flaps 5, 7, 9 and 11 which extend from these panels, constitute the sides of the box.

In closing the box, the flaps 11, extending from the closure section 10, are folded ontothe upper portions of the flaps 5 and 9 at points immediately above the flaps 7. The narrow front flap 12, extending from the front edge of the closure section, is folded onto the outer face of the front wall section 4, the narrow extensions 13 being folded 'backwardly to lie within the side walls of the box at points between the flaps l1 and 5. The closure may then be secured in any suitable manner, preferably by means of a cord 14 arranged around the box as shown in Fig. V.

The side walls of the box are formed by the flaps 5, 7, 9 and 11. The vertical edges of the flaps 5 and 9 abut against each other, and the lower edge of each flap 11 abuts against the upper edge of a flap 7. By forming the flaps as shown in Fig. I and folding them as shown in Figs. II and V, I produce a box having very strong side walls which brace the structure very materially, and which are well adapted to withstand the stresses to which they are subjected in service. The flaps-5 abut against the flaps 9 to form approximately continuous wall members, and these members are reinforced by the flaps 7 and 11 which also abut against each other. Another advantage is the saving of material gained by abutting the flaps against each other, as just described, instead of lapping them at points where the lapped portions would not materially reinforce each other.

A most important feature of the invention consists of the front closure flap 12 and its foldable extensions 13 which lie within the side walls of the box when the parts are folded to the positions shown in Fig. V. hen the box is closed and fastened (Fig. V) the extensions 13 serve as anchors for holding the front flap 12 in engagement with, or close to, the front wall 4, thus preventing a person from reaching into the box by lifting the front flap 12 and inserting his hand between the closure and the front wall 4.

Fig. VI illustrates a box having flaps 5 and 9 which extend from the wall sections 4 and 8 the bottom wall section being provided with flaps 7 engaging the outer faces of said flaps 5 and 9 The flaps 7 extend to points near the upper portion of the box body, and each of the members 13*, extending from the front closure flap 12, is equal in width to the distance from the upper edge of a flap 7 to the upper edge of a flap 5 Whenthe box is closed these extensions 13 lie immediately above the flaps 7 The lower edge of each extension 13 rests upon the upper edge of a flap 7 while the upper edge of said extension 13" lies flush with the upper edges of the flaps 5 It will be apparent that the extensions 13? serve as means for reinforcing the box, in addition to constituting a highly desirable means for securing the front closure flaps 12 Fig. VII illustrates a closure provided with side flaps 11 which extendfrom the top 'to the bottom of the box. The bottom wall of this box has flaps 7 which also extend from the top to the bottom of the box. The flaps 5 and 9 extending from the front and rear walls, are similar to the corre-i sponding elements of Fig. II. The box shown in Fig. VIII is reinforced by the wide flaps 7 and 11", and when this box is folded, the extensions 18 will lie between said flaps 7 b and 11 to secure the front closure flap 12 1. A "paper box having front and rear panel members forming the front and rear walls of the box, a bottom panel member forming the bottom of the box, a closure in the form of a panel hinged to said rear Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.

panel member to constitute the top of the box, side flaps extending from said closure, and side flaps extending from said front,

rear and bottom panel members, said side flaps being folded to constitute the side walls of the box, said closure having a front flap which laps the upper portion of said front panel, and said front flap being provided at its ends with foldable extensions which extend backwardly and lie within the side walls of thebox at points between the'side flaps of the'closure panel and the sidefiaps of said front panel member.
